ABSTRACT: Controlling magnetism by electrical means is a key challenge to better information technology. Electrical control of magnetism has been explored in a variety of materials including dilute magnetic semiconductors, ferromagnetic metal thin films and multiferroics. The recently emerged atomically thin magnetic materials provide unprecedented opportunities to study magnetism in the 2D limit and engineer devices through van der Waals heterostructures. In particular, CrI3 is a model Isingferromagnet with intriguing layer-dependent magnetic order, whereas monolayer CrI3 is a ferromagnet and bilayer CrI3 is an antiferromagnet with two ferromagnetic monolayers coupled antiferromagnetically. In this talk, Prof. Shan will present her team's recent results on switching the interlayer magnetic order in CrI3 bilayers by either a pure electric field or electrostatic doping and she will discuss possible mechanisms for the observed effects in experiment.

BIOGRAPHY: Jie Shan is a professor of Applied and Engineering Physics and in Physics at Cornell University. She received her diploma in Mathematics and Physics from Moscow State University, Russia, in 1996 and her Ph.D. in Physics from Columbia University in 2001. Research in her group is focused on experimental studies of the electronic and optical properties of nanoscale materials. Current activities have involved the investigation of novel two-dimensional atomic crystals such as graphene and transition metal dichalcogenides.
